Hybrid Diff Instructions for Review

[TexasSP]

I am not wild about the teflon shims as stated in that link. I tried this and had wobble that was unacceptable so I stick with metal shims. Any size shim rings you need can easily be found at www.McMaster.com. I got the original instructions I used for shimming diffs years ago from someone on the TRX forums. It also had notes about shimming the pinion gear which helps a lot as well. Sometimes there is a lot of front/back play in the pinion gear against the ring.

Here's the instructions for assembling and shimming the diffs from UE. I used them for my 6 and 8 spider diffs:

WOW what a great thread.. Extremely well written, it should help out many of the newcomers for many years to come..

Great Job Sir..

Great job Arct1k, but just one thing missing, is for the front diff, when you reinstall the bulckhead on the frame, the little black plastic goodies who hold the stock diff in place have to be triming a little bit with a Dremel to give room for the new and bigger Hybrid alloy diff case.

Other than that, all is OK

Final Version unless anyone spots anything very wrong...

Cool. Except where does one find a 26t or 33t pinion?

It may be a good idea to add something about the pinion/spur ratio, and that you can also choose a smaller spur and not such an enormous (impossible in this case) leap in pinion size.

I guess this is hardly a gear selection tutorial sheet, but if you say its good to change the gearing if swapping in a lower ratio diff, then recommending a pinion size that's near impossible to get, it may be a good idea to put a word in about it. Or am I being pedantic?

[Arct1k]

Tough crowd! you can get a 25T - the 33T was to show that the gearing gets silly - The next paragraph says truggy diffs only for a novak HV setup...

Link fixed - It was case sensitive...

That is kind of the point...

Also you need to change the link to the rc-monster forum to
www.rc-monster.com/forum/

Leaving out the last back slash causes an invalid link.

Nice Arct1c!

Question: why do you say to make note of which diff is front or rear? Is it simply because of the oil differences? If that is it, you can always feel the difference in stiffness...

[Arct1k]

For the oil - I guess you can feel it but doesn't hurt to make a note...

question:
if I have the truggy diffs? can I just purchase the Hot Bodies 13T BEVEL GEAR? to make them buggie diffs? or is it not that simple?

sorry for my ignorance, I just purchased a G3R and it came these 1/8 truggy diffs but would prefer the buggy.

Yes but make sure the pinion and ring gear have the same cut. Some truggy gears are spiral cut. What brand are your current diffs?

hot bodies 43/10 truggy diffs

Then you're good to go.
